2.
Rebuild the kernel by running
/sbin/ddr_config
, then reboot the system with the tape
drive attached. The device files for the Ultrium drive will be generated in
/dev/tape and /
dev/ntape
when you reboot.
3. The names of the device files can be interpreted as follows:
Devices in the
/dev/ntape
directory are “no-rewind” devices. Those in
/dev/tape
will do
a rewind on close.
The device files then have the syntax:
tapeX_dn
For example,
/dev/ntape/tape66_d1
is a device file for device 66, no-rewind using
density number 1. Since all density numbers have the same parameters it does not matter
which density number file is used.
What Next?
Once the device files have been created, you should confirm that your new tape drive is working
properly. Chapter 7, “Verifying the Installation” provides instructions on backing up and restoring
a sample file to test your installation.
